As shown in FIG. 1, the display panel includes a display layered structure 510 and a lens layer 520. The lens layer 520 is spaced apart from the display layered structure 510, for example. The lens layer 520 includes, for example, a microlens array, and each microlens is implemented as, for example, a lenticular lens or a plano-convex lens. The lens layer 520 condenses the light emitted from the display stack structure 510 (or images the image displayed by the display stack structure 510), so that the user's eyes can better see the display of the display stack structure 510 at a position closer to the display panel. Image, so that the display panel can realize near-eye display, and therefore can be applied to smart glasses such as virtual reality glasses and augmented reality glasses. However, the inventor of the present disclosure noticed in research that the lens layer 520 provided separately from the display laminated structure 510 is thicker, thereby increasing the number of display devices (eg, virtual reality glasses and augmented reality glasses) including the display panel. Thickness and weight.
本公开的至少一个实施例提供了一种显示面板和显示装置。显示面板包括显示层叠结构和层叠于显示层叠结构的显示侧表面的静电释放层。显示层 叠结构包括显示区域,静电释放层包括透镜单元,透镜单元位于显示区域上。在一些实施例中,通过使得静电释放层包括透镜单元,可以使得显示面板和显示装置在具有静电释放、光会聚效果的同时还无需设置单独的透镜层,由此可以降低包括该显示面板的显示装置(例如,虚拟现实眼镜和增强现实眼镜)的厚度和重量。At least one embodiment of the present disclosure provides a display panel and a display device. The display panel includes a display laminated structure and an electrostatic discharge layer laminated on a display side surface of the display laminated structure. The display layered structure includes a display area, the electrostatic discharge layer includes a lens unit, and the lens unit is located on the display area. In some embodiments, by including the electrostatic discharge layer with a lens unit, the display panel and the display device can have the effects of electrostatic discharge and light convergence without having to provide a separate lens layer, thereby reducing the display including the display panel. The thickness and weight of devices such as virtual reality glasses and augmented reality glasses.
在一些示例中,静电释放层的透镜单元具有光会聚效果是指透镜单元可以使得源于显示层叠结构的且入射在透镜单元上的光线在从透镜单元出射时具有更小的发散角,而不要求从透镜单元出射的光线为会聚光。例如,在从透镜单元出射的光线为发散光或接近于平行光的发散光时,显示面板的用户观察到的图像为虚像;又例如,在从透镜单元出射的光线为发会聚光时,显示面板的用户观察到的图像为实像。需要说明的是,本公开的至少一个实施例提供的显示面板和显示装置可以根据实际应用需求提供虚像或实像,在此不再赘述。In some examples, the lens unit of the electrostatic discharge layer has a light-converging effect, which means that the lens unit can make light from the display laminated structure and incident on the lens unit have a smaller divergence angle when exiting from the lens unit, without It is required that the light emitted from the lens unit is convergent light. For example, when the light emitted from the lens unit is divergent light or divergent light close to parallel light, the image observed by the user of the display panel is a virtual image; for example, when the light emitted from the lens unit is convergent light, the display The image observed by the panel user is a real image. It should be noted that the display panel and the display device provided by at least one embodiment of the present disclosure may provide a virtual image or a real image according to actual application requirements, and details are not described herein again.
下面通过几个示例对本公开的实施例提供的显示面板进行非限制性的说明,如下面所描述的,在不相互抵触的情况下这些具体示例中不同特征可以相互组合,从而得到新的示例,并且,这些新的示例也都属于本公开保护的范围。The following is a non-limiting description of the display panel provided by the embodiments of the present disclosure through several examples. As described below, different features in these specific examples can be combined with each other without conflicting each other, thereby obtaining a new example. And, these new examples also belong to the scope of protection of the present disclosure.
图2示出了本公开的至少一个实施例提供的显示面板100的截面示意图,该显示面板100可以应用于诸如虚拟现实显示装置和增强现实显示装置等近眼显示装置或头戴式显示装置中。FIG. 2 illustrates a schematic cross-sectional view of a display panel 100 provided by at least one embodiment of the present disclosure. The display panel 100 may be applied to a near-eye display device or a head-mounted display device such as a virtual reality display device and an augmented reality display device.
如图2所示,该显示面板100包括显示层叠结构110和层叠于显示层叠结构110的显示侧表面111的静电释放层120。例如,静电释放层120由透明导电材料制成,静电释放层120例如可以接地,以释放显示面板在例如操作、运输过程中产生的静电,以为显示面板提供保护作用(例如,静电防护功能)。在一些示例中,透明导电材料可以包括石墨烯,由此可以提升静电释放层120的导电性能以及透光性能;在另外一些示例中,静电释放层120的透明导电材料还可以包括下述材料的至少一种:铟锡氧化物(indium tin oxide,ITO)、铟锌氧化物(indium zinc oxide,IZO)、镉锡氧化物(cadmium tin oxide,CTO)、氧化锡(stannum dioxide,SnO2)以及氧化锌(zinc oxide,ZnO)等。As shown in FIG. 2, the display panel 100 includes a display laminated structure 110 and an electrostatic discharge layer 120 laminated on a display side surface 111 of the display laminated structure 110. For example, the electrostatic discharge layer 120 is made of a transparent conductive material. For example, the electrostatic discharge layer 120 can be grounded to discharge static electricity generated by the display panel during, for example, operation and transportation, so as to provide a protection function for the display panel (for example, an electrostatic protection function). In some examples, the transparent conductive material may include graphene, thereby improving the conductivity and light transmission performance of the electrostatic discharge layer 120. In other examples, the transparent conductive material of the electrostatic discharge layer 120 may further include the following materials: At least one: indium tin oxide (ITO), indium zinc oxide (IZO), cadmium tin oxide (CTO), stannum oxide (SnO2), and oxide Zinc (zinc oxide, ZnO), etc.
例如,由于显示层叠结构110与静电释放层120直接接触,因此静电释放层120可以及时地将显示层叠结构110上累积的静电荷导出显示层叠结构 110,并因此可以避免累积的静电荷对显示层叠结构110的不利影响。For example, since the display laminated structure 110 is in direct contact with the electrostatic discharge layer 120, the electrostatic discharge layer 120 can lead the electrostatic charge accumulated on the display laminated structure 110 to the display laminated structure 110 in a timely manner, and thus can prevent the accumulated electrostatic charge from stacking on the display. Adverse effects of structure 110.
如图3A所示,显示层叠结构110包括显示区域112和围绕显示区域112的周边区域113。如图3A和图3B所示,静电释放层120包括透镜单元121,并且透镜单元121位于显示区域112上。例如,透镜单元121在显示层叠结构110上的正投影与显示区域112重叠(例如,完全重叠)。例如,静电释放层120包括的透镜单元121可以会聚显示层叠结构110的显示区域112发射的光线,并使得用户的眼睛在距离显示面板较近的位置也能较好地看到显示层叠结构110显示的图像。相比于图1示出的显示面板,由于本公开的实施例提供的显示面板100无需设置与显示层叠结构110分立设置的透镜层,因此可以降低包括该显示面板的显示装置(例如,虚拟现实眼镜和增强现实眼镜)的厚度和重量,进而提升了用户的使用体验。As shown in FIG. 3A, the display stack structure 110 includes a display area 112 and a peripheral area 113 surrounding the display area 112. As shown in FIGS. 3A and 3B, the electrostatic discharge layer 120 includes a lens unit 121, and the lens unit 121 is located on the display area 112. For example, the orthographic projection of the lens unit 121 on the display stack structure 110 overlaps (eg, completely overlaps) the display area 112. For example, the lens unit 121 included in the electrostatic discharge layer 120 can condense the light emitted from the display area 112 of the display stack structure 110 and make the user's eyes better see the display of the display stack structure 110 at a position closer to the display panel. Image. Compared with the display panel shown in FIG. 1, since the display panel 100 provided by the embodiment of the present disclosure does not need to provide a lens layer separately from the display stack structure 110, a display device (for example, virtual reality) including the display panel can be reduced. Thickness and weight of glasses and augmented reality glasses), thereby improving the user experience.
例如,透镜单元121的具体类型和结构可以根据实际应用需求进行设定,本公开的实施例对此不做具体限定。For example, the specific type and structure of the lens unit 121 can be set according to actual application requirements, which is not specifically limited in the embodiments of the present disclosure.
例如,如图4A-图4F所示,透镜单元121可以实现为菲涅尔透镜单元,由此可以降低透镜单元121的厚度,并进一步地降低显示面板100的厚度和重量。菲涅尔透镜单元的具体结构和参数可以根据实际应用需求进行设定,本公开的实施例对此不做具体限定。For example, as shown in FIGS. 4A to 4F, the lens unit 121 may be implemented as a Fresnel lens unit, thereby reducing the thickness of the lens unit 121 and further reducing the thickness and weight of the display panel 100. The specific structure and parameters of the Fresnel lens unit can be set according to actual application requirements, which are not specifically limited in the embodiments of the present disclosure.
例如,菲涅尔透镜单元可以实现为图4A所示的菲涅尔透镜或其适当的变型。如图4A所示,菲涅尔透镜单元的表面可以包括位于中心部分的弧面(椭球型弧面)以及位于周边区域的锯齿型凹槽;每个凹槽的宽度(在凹槽排布方向上的宽度)例如相等;例如,每个凹槽的角度与相邻凹槽的角度不同,凹槽的角度是指形成凹槽的两个表面之间的夹角。For example, the Fresnel lens unit may be implemented as a Fresnel lens shown in FIG. 4A or an appropriate modification thereof. As shown in FIG. 4A, the surface of the Fresnel lens unit may include a curved surface (ellipsoidal curved surface) located in the center portion and a sawtooth-shaped groove located in the peripheral area; the width of each groove (arranged in the grooves) The width in the direction) is, for example, equal; for example, the angle of each groove is different from the angle of an adjacent groove, and the angle of the groove refers to the angle between the two surfaces forming the groove.
如图4A所示,静电释放层120包括的菲涅尔透镜单元可以会聚入射其上的光线(例如,入射其上的实质上平行的光线或具有较小发散角的光线),因此使得用户的眼睛在距离显示面板较近的位置也能较好地看到显示层叠结构110显示的图像。相比于图1示出的显示面板,由于本公开的实施例提供的显示面板100无需设置与显示层叠结构110分立设置的透镜层,因此可以降低显示面板100的厚度和重量,进而提升了用户的使用体验。As shown in FIG. 4A, the Fresnel lens unit included in the electrostatic discharge layer 120 can converge light rays incident thereon (for example, substantially parallel light rays incident thereon or light rays having a small divergence angle), thus making the user's The eye can also better see the image displayed by the display stack structure 110 at a position closer to the display panel. Compared with the display panel shown in FIG. 1, since the display panel 100 provided by the embodiment of the present disclosure does not need to provide a lens layer separately from the display laminated structure 110, the thickness and weight of the display panel 100 can be reduced, thereby improving users. Experience.
例如,根据实际应用需求,如图4B-图4D所示,菲涅尔透镜单元还可以实现为相位型菲涅尔透镜,由此可以降低菲涅尔透镜单元的制作难度。例如,相位型菲涅尔透镜可以为二台阶菲涅尔透镜、四台阶菲涅尔透镜、八台阶菲 涅尔透镜、十六台阶菲涅尔透镜或者其它适用的菲涅尔透镜。例如,图4C示出了二台阶菲涅尔透镜的平面示意图,图4D示出了二台阶菲涅尔透镜、四台阶菲涅尔透镜和八台阶菲涅尔透镜的剖面示意图。需要说明的是,图4D示出的台阶分布表示菲涅尔透镜的相位分布。For example, according to actual application requirements, as shown in FIGS. 4B to 4D, the Fresnel lens unit may also be implemented as a phase-type Fresnel lens, thereby reducing the difficulty of manufacturing the Fresnel lens unit. For example, the phase Fresnel lens may be a two-step Fresnel lens, a four-step Fresnel lens, an eight-step Fresnel lens, a sixteen-step Fresnel lens, or other applicable Fresnel lenses. For example, FIG. 4C shows a schematic plan view of a two-step Fresnel lens, and FIG. 4D shows a cross-sectional view of a two-step Fresnel lens, a four-step Fresnel lens, and an eight-step Fresnel lens. It should be noted that the step distribution shown in FIG. 4D represents the phase distribution of the Fresnel lens.
例如,如图4B-图4D所示,菲涅尔透镜可以包括M个光栅单元1111(例如,相位光栅单元),M为正整数(M的具体数值可以基于菲涅尔透镜的尺寸进行设定),每个光栅单元1111中可以包括N=2 m(m=1、2、3……)个台阶,对于二台阶菲涅尔透镜、四台阶菲涅尔透镜和八台阶菲涅尔透镜,m的取值分别为1、2和3。例如,,每个台阶对入射其上的光线引起的相位改变(例如,菲涅尔透镜的相邻台阶所在的区域之间的相位差)可以为2π/N,台阶高度可以为h=λ/(N×(n1-n2));此处,λ为入射到菲涅尔透镜上的光线波长(在入射光为白光复色光的情况下,λ的取值例如可以为587nm),n1为菲涅尔透镜的折射率(例如,n1=1.4918),n2为菲涅尔透镜周边介质的折射率(例如,n2=1)。 For example, as shown in FIGS. 4B-4D, the Fresnel lens may include M grating units 1111 (for example, a phase grating unit), where M is a positive integer (the specific value of M may be set based on the size of the Fresnel lens) ), Each grating unit 1111 may include N = 2 m (m = 1, 2, 3, ...) steps. For a two-step Fresnel lens, a four-step Fresnel lens, and an eight-step Fresnel lens, The values of m are 1, 2 and 3, respectively. For example, the phase change caused by the light incident on each step (for example, the phase difference between the regions where adjacent steps of the Fresnel lens are located) can be 2π / N, and the step height can be h = λ / (N × (n1-n2)); Here, λ is the wavelength of the light incident on the Fresnel lens (in the case where the incident light is white light polychromatic light, the value of λ can be 587nm, for example), and n1 is phenanthrene The refractive index of the Niesle lens (for example, n1 = 1.4918), and n2 is the refractive index of the medium surrounding the Fresnel lens (for example, n2 = 1).
例如,如图4C所示,对于二台阶相位型菲涅尔透镜,rj,1(也即,r j,1)和rj,2(也即,r j,2)为第j个光栅单元1111中的环带半径,此处j为小于或等于M的正整数。例如,rj,1和rj,2与焦距值f′、物方和像方介质的折射率n以及入射光线的波长满足以下关系: For example, as shown in FIG. 4C, for a two-step phase Fresnel lens, rj, 1 (that is, r j, 1 ) and rj, 2 (that is, r j, 2 ) are the j-th grating unit 1111 The ring zone radius in, where j is a positive integer less than or equal to M. For example, rj, 1 and rj, 2 satisfy the following relationship with the focal length value f ′, the refractive index n of the object-side and image-side media, and the wavelength of the incident light:

二台阶菲涅尔透镜的台阶宽度dj,1(也即,d j,1)和dj,2(也即,d j,2)分别满足以下公式: The step widths dj, 1 (ie, d j, 1 ) and dj, 2 (ie, d j, 2 ) of the two-step Fresnel lens satisfy the following formulas, respectively:
d j,1=r j,1-r j-1,2 d j, 1 = r j, 1 -r j-1,2
d j,2=r j,2-r j,1d j, 2 = r j, 2 -r j, 1 .
例如,如图4D所示,对于N个台阶相位型菲涅尔透镜,每个光栅单元1111中具有N-1个相同宽度的台阶(N-1个相同宽度的台阶顺次相接),剩余的一个台阶(位于相位型菲涅尔透镜的中心区域)的宽度与上述N-1个台阶的宽度不同,第j光栅单元1111中N-1个台阶的宽度tj,2(也即,t j,2)以及第 j光栅单元1111中剩余台阶的宽度tj,1(也即,t j,1)分别满足以下公式: For example, as shown in FIG. 4D, for N step phase Fresnel lenses, each grating unit 1111 has N-1 steps of the same width (N-1 steps of the same width are sequentially connected), and the remaining The width of one step (located in the center region of the phase-type Fresnel lens) is different from the width of the above N-1 steps. The width of the N-1 steps in the j-th grating unit 1111 is tj, 2 (that is, t j , 2 ) and the width tj, 1 (ie, t j, 1 ) of the remaining steps in the j-th grating unit 1111 respectively satisfy the following formulas:

图4B-图4D所示的菲涅尔透镜单元可以会聚入射其上的光线(例如,实质上平行的光线或具有较小发散角的光线),并因此使得用户的眼睛能够看到显示层叠结构110显示的图像。相比于图1示出的显示面板,由于本公开的实施例提供的显示面板100无需设置与显示层叠结构110分立设置的透镜层,因此可以降低显示面板100的厚度和重量,进而提升了用户的使用体验。The Fresnel lens unit shown in FIGS. 4B to 4D can converge light rays incident thereon (for example, substantially parallel light rays or light rays having a small divergence angle), and thus enable a user's eyes to see the display laminated structure. 110 displayed images. Compared with the display panel shown in FIG. 1, since the display panel 100 provided by the embodiment of the present disclosure does not need to provide a lens layer separately from the display laminated structure 110, the thickness and weight of the display panel 100 can be reduced, thereby improving users. Experience.
需要说明的是,根据实际应用需求,菲涅尔透镜单元还可以实现为图4E或图4F示出的菲涅尔透镜,在此不再赘述。It should be noted that, according to actual application requirements, the Fresnel lens unit may also be implemented as the Fresnel lens shown in FIG. 4E or FIG. 4F, and details are not described herein again.
例如,根据实际应用需求,本公开的实施例提供的透镜单元121还可以实现为基于超表面相位调节原理的微纳透镜或者基于全息材料的微透镜。需 要说明的是,本公开的实施例提供的透镜单元121不限于实现为菲涅尔透镜单元、基于超表面相位调节原理的微纳透镜或者基于全息材料的微透镜,本公开的实施例提供的透镜单元121还可以实现为其它适用的透镜,只要透镜单元121由透明导电材料制成即可,在此不再赘述。For example, according to actual application requirements, the lens unit 121 provided in the embodiment of the present disclosure may also be implemented as a micro / nano lens based on a supersurface phase adjustment principle or a micro lens based on a holographic material. It should be noted that the lens unit 121 provided in the embodiment of the present disclosure is not limited to being implemented as a Fresnel lens unit, a micro-nano lens based on the principle of supersurface phase adjustment, or a micro-lens based on a holographic material. The lens unit 121 may also be implemented as other applicable lenses, as long as the lens unit 121 is made of a transparent conductive material, and details are not described herein again.
如图5A所示,透镜单元121包括平坦面122和与平坦面122相对的非平坦面123(例如,图4B和图4D示出的阶梯面)。并且,相比于平坦面122,非平坦面123远离显示层叠结构110。又例如,在一些示例中,相比于平坦面122,非平坦面123还可以靠近显示层叠结构110,在此不再赘述。As shown in FIG. 5A, the lens unit 121 includes a flat surface 122 and a non-flat surface 123 (for example, a stepped surface shown in FIGS. 4B and 4D) opposite the flat surface 122. Moreover, compared with the flat surface 122, the non-flat surface 123 is far from the display stack structure 110. For another example, in some examples, the non-planar surface 123 may be closer to the display stack structure 110 than the flat surface 122, and details are not described herein again.
如图5A和图5B所示,在一些示例中,显示面板100还包括平坦化层124;平坦化层124覆盖在非平坦面123上,以将静电释放层120的设置了非平坦面123一侧的表面平坦化,由此使得其它膜层可以更好的贴合在静电释放层120上。例如,平坦化层124的折射率小于透镜单元121的折射率,以避免平坦化层124影响透镜单元121的性能。As shown in FIG. 5A and FIG. 5B, in some examples, the display panel 100 further includes a planarization layer 124; the planarization layer 124 covers the non-planar surface 123, so that the non-planar surface 123 of the electrostatic discharge layer 120 is provided. The side surface is flattened, so that other film layers can better adhere to the electrostatic discharge layer 120. For example, the refractive index of the planarization layer 124 is smaller than the refractive index of the lens unit 121 to prevent the planarization layer 124 from affecting the performance of the lens unit 121.
例如,如图6所示,显示层叠结构110可以配置为液晶显示层叠结构;此时,显示层叠结构110包括顺次设置的背光源134、阵列基板133、液晶层132和彩膜基板131。彩膜基板131包括第一彩色滤光单元135、第二彩色滤光单元136和第三彩色滤光单元137,第一彩色滤光单元135、第二彩色滤光单元136和第三彩色滤光单元137的颜色彼此不同(例如,分别为红色滤光片、绿色滤光片和蓝色滤光片)。例如,背光源134、阵列基板133、液晶层132和彩膜基板131的具体结构可以参见相关技术,在此不再赘述。需要说明的是,在一些实施例中,阵列基板和彩膜基板可以结合为一个基板并设置在液晶层的一侧;在此种情况下,可以对图6示出的显示层叠结构110做适应性修改,在此不再赘述。For example, as shown in FIG. 6, the display stack structure 110 may be configured as a liquid crystal display stack structure; at this time, the display stack structure 110 includes a backlight 134, an array substrate 133, a liquid crystal layer 132, and a color filter substrate 131 which are sequentially disposed.

For example, for specific structures of the backlight 134, the array substrate 133, the liquid crystal layer 132, and the color filter substrate 131, refer to related technologies, and details are not described herein again. It should be noted that, in some embodiments, the array substrate and the color filter substrate may be combined into one substrate and disposed on one side of the liquid crystal layer; in this case, the display stack structure 110 shown in FIG. 6 may be adapted. Modifications are not repeated here.

As shown in FIG. 6, the first polarizer 116 is attached to a side of the electrostatic discharge layer 120 away from the display stack structure 110. For example, the first polarizer 116 may be attached to a plane of the planarization layer 124 away from the display stack structure 110. On the side surface. The second polarizer is disposed between the backlight 134 and the array substrate 133. The first polarizer 116 and the second polarizer are implemented as, for example, linear polarizers, and are configured to work in cooperation with the liquid crystal layer 132 to control the intensity of light output by the display panel 100.
例如,根据实际应用需求,显示层叠结构110还可以配置为自发光式显示层叠结构,自发光式显示层叠结构可以实现为有机发光二极管显示层叠结 构和量子点显示层叠结构。For example, according to actual application requirements, the display stack structure 110 may also be configured as a self-emissive display stack structure, and the self-emissive display stack structure may be implemented as an organic light emitting diode display stack structure and a quantum dot display stack structure.
图8是本公开的至少一个实施例提供的一种包括自发光式显示层叠结构的显示面板的截面示意图。例如,如图8所示,显示层叠结构110(自发光式显示层叠结构)包括第二电极142、功能层143、第一电极141和防护基板144。第二电极142例如为阴极(例如,包括金属),第一电极141例如为阳极。功能层143包括发光层146(有机发光层或量子点发光层),发光层146包括第一发光单元171、第二发光单元172和第三发光单元173。在一些示例中,第一发光单元171、第二发光单元172和第三发光单元173发射的光线161颜色彼此不同;在另外一些示例中,第一发光单元171、第二发光单元172和第三发光单元173发射的光线161的颜色均相同,在此种情况下,可以通过在功能层143的出光侧设置不同颜色的滤光片实现显示层叠结构110的彩色显示。在一些示例中,功能层143还可以包括空穴传输层145和电子传输层147等。FIG. 8 is a schematic cross-sectional view of a display panel including a self-emissive display laminated structure provided by at least one embodiment of the present disclosure. For example, as shown in FIG. 8, the display stack structure 110 (self-emissive display stack structure) includes a second electrode 142, a functional layer 143, a first electrode 141, and a protective substrate 144. The second electrode 142 is, for example, a cathode (for example, includes a metal), and the first electrode 141 is, for example, an anode. The functional layer 143 includes a light emitting layer 146 (an organic light emitting layer or a quantum dot light emitting layer), and the light emitting layer 146 includes a first light emitting unit 171, a second light emitting unit 172, and a third light emitting unit 173. In some examples, the colors of light 161 emitted by the first, second, and third light emitting units 171, 172, and 173 are different from each other; in other examples, the first, second, and third light emitting units 171, 172, and 173 are different in color from each other; The colors of the light 161 emitted by the light emitting unit 173 are all the same. In this case, a color display of the display stack structure 110 may be implemented by setting filters of different colors on the light-exiting side of the functional layer 143. In some examples, the functional layer 143 may further include a hole transport layer 145, an electron transport layer 147, and the like.
例如,防护基板144可以是玻璃基板、石英基板、塑料基板(例如聚对苯二甲酸乙二醇酯(PET)基板)或者由其它适合的材料制成的基板。例如,如图4B和图8所示,在显示层叠结构110配置为自发光式显示层叠结构的情况下,静电释放层120以及静电释放层120包括的透镜单元121经由平坦面122和防护基板144层叠在显示层叠结构110的显示侧表面111。For example, the protective substrate 144 may be a glass substrate, a quartz substrate, a plastic substrate (such as a polyethylene terephthalate (PET) substrate), or a substrate made of other suitable materials. For example, as shown in FIGS. 4B and 8, in a case where the display laminated structure 110 is configured as a self-emissive display laminated structure, the electrostatic discharge layer 120 and the lens unit 121 included in the electrostatic discharge layer 120 pass through the flat surface 122 and the protective substrate 144.

The polarizer 115 is implemented as, for example, a circular polarizer to reduce the intensity of the reflected light caused by the reflection of the display laminated structure 110 and thus reduce the adverse effect of the reflected light on the quality of the image displayed by the display laminated structure 110. As shown in FIG. 8, the polarizer 115 may be attached to a surface of the planarization layer 124 away from the display stack structure 110, but embodiments of the present disclosure are not limited thereto.
例如,如图5B、图6和图8所示,静电释放层120包括多个透镜单元121,多个透镜单元121例如阵列排布;显示层叠结构110(例如,显示层叠结构110的显示区域112)包括多个显示子像素114(多个阵列排布的显示子像素114),并且多个显示子像素114和多个透镜单元121一一对应,由此可以提升用户的眼睛观察到的图像的质量。例如,多个透镜单元121在显示层叠结构110上的正投影分别与多个显示子像素114重叠(例如,完全重叠)。例如,如图6所示,第一彩色滤光单元135、第二彩色滤光单元136和第三彩色滤光单元137分别对应一个显示子像素114(分别设置在对应的一个显示子像素 114中),并且每个显示子像素114对应于一个透镜单元121;例如,每个显示子像素114在静电释放层120上的正投影与对应的透镜单元121重合(例如,完全重合)。又例如,如图8所示,第一发光单元171、第二发光单元172和第三发光单元173发射分别对应于一个显示子像素114(分别设置在对应的一个显示子像素114中),并且每个显示子像素114对应一个透镜单元121。For example, as shown in FIG. 5B, FIG. 6 and FIG. 8, the electrostatic discharge layer 120 includes a plurality of lens units 121, for example, an array of a plurality of lens units 121; a display stack structure 110 (for example, a display area 112 of the display stack structure 110) ) Includes a plurality of display sub-pixels 114 (a plurality of display sub-pixels 114 arranged in an array), and the plurality of display sub-pixels 114 correspond to the plurality of lens units 121, thereby improving the image observed by the user's eyes. quality. For example, the orthographic projections of the plurality of lens units 121 on the display stack structure 110 overlap (eg, completely overlap) the plurality of display sub-pixels 114, respectively. For example, as shown in FIG. 6, the first color filter unit 135, the second color filter unit 136, and the third color filter unit 137 respectively correspond to one display sub-pixel 114 (respectively disposed in the corresponding one display sub-pixel 114). ), And each display sub-pixel 114 corresponds to one lens unit 121; for example, the orthographic projection of each display sub-pixel 114 on the electrostatic discharge layer 120 coincides with the corresponding lens unit 121 (for example, completely coincides). As another example, as shown in FIG. 8, the first light-emitting unit 171, the second light-emitting unit 172, and the third light-emitting unit 173 emit light corresponding to one display sub-pixel 114 (each provided in the corresponding one display sub-pixel 114), and Each display sub-pixel 114 corresponds to a lens unit 121.
需要说明的是,本公开的实施例提供的显示面板100不限于配置为显示子像素114和透镜单元121一一对应;根据实际应用需求,每个透镜单元121还可以对应于第一数目的透镜单元121,此处,第一数目小于静电释放层120包括的透镜单元121的数目且大于1,由此可以减少菲涅尔透镜单元的设置个数并降低静电释放层120的加工难度。例如,静电释放层120可以仅设置一个透镜单元121(例如,相位型菲涅尔透镜单元),并且该透镜单元121对应于显示层叠结构110的所有显示子像素114。It should be noted that the display panel 100 provided by the embodiment of the present disclosure is not limited to being configured to display one-to-one correspondence between the display sub-pixel 114 and the lens unit 121; according to actual application requirements, each lens unit 121 may also correspond to a first number of lenses Here, the first number of units 121 is less than the number of lens units 121 included in the electrostatic discharge layer 120 and is greater than 1, thereby reducing the number of Fresnel lens units provided and reducing the processing difficulty of the electrostatic discharge layer 120. For example, the electrostatic discharge layer 120 may be provided with only one lens unit 121 (for example, a phase-type Fresnel lens unit), and the lens unit 121 corresponds to all the display sub-pixels 114 of the display stack structure 110.
需要说明的是,在静电释放层120包括多个透镜单元121情况下,多个透镜单元121之间彼此电连接(例如,相邻的透镜单元121彼此相接但不重叠),由此可以保证静电释放层120能够将累积在显示层叠结构上的静电荷导出显示面板。It should be noted that when the electrostatic discharge layer 120 includes a plurality of lens units 121, the plurality of lens units 121 are electrically connected to each other (for example, adjacent lens units 121 are in contact with each other but do not overlap), thereby ensuring that The electrostatic discharge layer 120 can lead the electrostatic charges accumulated on the display laminated structure to the display panel.
如图7和图9所示,在一些示例中,显示面板100还包括电压控制电路151,电压控制电路151与静电释放层120连接且配置为向静电释放层120施加电压(例如,1V-10V),由此可以更好地将静电释放层120上累积的静电荷导出显示面板100。例如,该电压控制电路可以采用可变分压电路,与***电源电压连接,通过调节分压从而向静电释放层输出控制电压。As shown in FIGS. 7 and 9, in some examples, the display panel 100 further includes a voltage control circuit 151 connected to the electrostatic discharge layer 120 and configured to apply a voltage (for example, 1V-10V) to the electrostatic discharge layer 120. ), So that the electrostatic charge accumulated on the electrostatic discharge layer 120 can be better led out of the display panel 100. For example, the voltage control circuit may use a variable voltage divider circuit, which is connected to the system power voltage, and outputs a control voltage to the electrostatic discharge layer by adjusting the voltage divider.
例如,在静电释放层120包括石墨烯,且在静电释放层120上施加电压的情况下,静电释放层120中石墨烯的碳分子将产生声子、离子和电子;产生的声子、离子和电子与碳分子团簇之间的相互摩擦、碰撞(例如,布朗运动)并因此产生热能,热能又可以转换为远红外线162,且远红外线162从静电释放层120辐射输出(例如,均匀地辐射输出)。例如,静电释放层120可以辐射位于5-14微米(例如,9-12微米)波段的远红外线162。例如,由于,静电释放层120可以辐射的远红外线162与人体辐射的红外线波长接近(例如,实质上相同),静电释放层120辐射的远红外线162可与人体细胞产生共振,并因此促进眼部血液循环、活化眼部细胞、增强眼部供氧、恢复睫状肌弹性、带动微循环网的氧气及养分交换、排除积存眼周的疲劳有害物质和乳酸等以 及缓和酸痛;由此在一些示例中,显示面板100可以舒缓眼部疲劳,并因此可以提升用户体验。For example, when the electrostatic discharge layer 120 includes graphene and a voltage is applied to the electrostatic discharge layer 120, carbon molecules of the graphene in the electrostatic discharge layer 120 will generate phonons, ions, and electrons; the generated phonons, ions, and The mutual friction and collision between electrons and carbon molecular clusters (for example, Brownian motion) and thus generate thermal energy, which can be converted into far-infrared 162, and the far-infrared 162 radiates output from the electrostatic discharge layer 120 (for example, uniformly radiates Output). For example, the electrostatic discharge layer 120 may radiate far-infrared rays 162 in a 5-14 micron (eg, 9-12 micron) band. For example, since the far-infrared radiation 162 that the electrostatic discharge layer 120 can radiate has a wavelength close to (for example, substantially the same as) the infrared radiation radiated from the human body, the far-infrared radiation 162 radiated from the electrostatic discharge layer 120 can resonate with human cells and thus promote the eyes Blood circulation, activation of eye cells, enhancement of oxygen supply to the eye, restoration of ciliary muscle elasticity, oxygen and nutrient exchange of the microcirculation network, elimination of accumulated harmful substances and lactic acid around the eyes, and relief of soreness; thus in some examples In the display panel 100, eye fatigue can be relieved, and thus the user experience can be improved.
例如,静电释放层120的电能-热能转换率可以大于99%。例如,静电释放层120可以具有优良的导电性,由此可以保证静电释放层120具有均匀的温度分布(例如,静电释放层120的温度的处处相等),并因此使得静电释放层120可以均匀地辐射红外线。For example, the electrical-to-thermal energy conversion rate of the electrostatic discharge layer 120 may be greater than 99%. For example, the electrostatic discharge layer 120 may have excellent electrical conductivity, thereby ensuring that the electrostatic discharge layer 120 has a uniform temperature distribution (for example, the temperature of the electrostatic discharge layer 120 is equal everywhere), and thus the electrostatic discharge layer 120 may be uniformly distributed. Radiation infrared.
例如,在静电释放层120上施加的电压不同的情况下,石墨烯的碳分子中产生的声子、离子和电子具有的动能不同,因此,静电释放层120的温度不同。如图7和图9所示,在一些示例中,显示面板100还包括温度控制电路152,温度控制电路152与静电释放层120连接且配置为获取静电释放层120的温度信息且根据温度信息控制电压控制电路151向静电释放层120施加的电压,由此调节静电释放层120的温度。例如,温度控制电路152可以包括热电偶电路、红外探测电路等以检测静电释放层120的温度,由此通过温度控制电路152可以使得静电释放层120的温度保持在38-42度的温度范围内。又例如,还可以通过温度控制电路152使得静电释放层120的温度保持在40度。For example, when different voltages are applied to the electrostatic discharge layer 120, phonons, ions, and electrons generated in the carbon molecules of graphene have different kinetic energy, and therefore, the temperature of the electrostatic discharge layer 120 is different. As shown in FIGS. 7 and 9, in some examples, the display panel 100 further includes a temperature control circuit 152 that is connected to the electrostatic discharge layer 120 and is configured to obtain temperature information of the electrostatic discharge layer 120 and control the temperature information according to the temperature information. The voltage applied by the voltage control circuit 151 to the electrostatic discharge layer 120, thereby adjusting the temperature of the electrostatic discharge layer 120. For example, the temperature control circuit 152 may include a thermocouple circuit, an infrared detection circuit, and the like to detect the temperature of the electrostatic discharge layer 120, and thus the temperature of the electrostatic discharge layer 120 may be maintained within a temperature range of 38-42 degrees through the temperature control circuit 152. . As another example, the temperature of the electrostatic discharge layer 120 can be maintained at 40 degrees by the temperature control circuit 152.

For example, the graphene material used can be prepared by itself or obtained from outsourcing.

For example, for a specific process flow of a deposition method, an imprint method, a machining method, or an etching method, refer to related technologies, and details are not described herein again.
在一些示例中,在步骤S10之后,且在步骤S20之前,还包括减薄显示层叠结构。例如,在显示层叠结构实现为液晶显示层叠结构,且静电释放层与彩膜基板直接接触的情况下,可以通过减薄彩膜基板包括的衬底基板的厚度来减薄显示层叠结构。又例如,在显示层叠结构实现为自发光式显示层叠结构,且静电释放层与防护基板直接接触的情况下,可以通过减薄防护基板的厚度来减薄显示层叠结构。In some examples, after step S10 and before step S20, the method further includes thinning the display stack structure. For example, when the display laminated structure is implemented as a liquid crystal display laminated structure and the electrostatic discharge layer is in direct contact with the color filter substrate, the display stacked structure can be thinned by reducing the thickness of the base substrate included in the color film substrate. For another example, when the display laminated structure is implemented as a self-emitting display laminated structure and the electrostatic discharge layer is in direct contact with the protective substrate, the display laminated structure can be thinned by reducing the thickness of the protective substrate.

例如,平坦化层可以采用透明绝缘材料形成,平坦化层例如可以采用有机树脂或例如氧化硅(SiOx)、氧氮化硅(SiNxOy)或者氮化硅(SiNx)等无机绝缘材料形成。For example, the planarization layer may be formed of a transparent insulating material, and the planarization layer may be formed of, for example, an organic resin or an inorganic insulating material such as silicon oxide (SiOx), silicon oxynitride (SiNxOy), or silicon nitride (SiNx).
例如,通过使得静电释放层包括透镜单元,可以降低该显示面板的制作方法制作的显示面板的厚度和重量,并因此可以提升用户的使用体验。For example, by making the electrostatic discharge layer include a lens unit, the thickness and weight of the display panel manufactured by the manufacturing method of the display panel can be reduced, and thus the user experience can be improved.
